Disclosed in the present invention are a
waste collection device, a waste liquid collection and
treatment system, and a docking method for the waste liquid collection and
treatment system. The
waste collection device is used for docking with a docking device (30) and comprises a plurality of collection joints; the plurality of collection joints comprise a liquid
discharge female joint (1601), a flushing female joint (1602) and a steam female joint (1603); the liquid
discharge female joint (1601) and the flushing female joint (1602) are arranged in a floating mode; the docking device (30) comprises a plurality of docking joints; the plurality of docking joints comprise a liquid
discharge male joint (3401), a flushing male joint (3402) and a steam male joint (3403). According to the
waste collection device, the waste liquid collection and
treatment system, and the docking method for the waste liquid collection and treatment
system, steam cleaning can be carried out on the waste liquid collection and treatment
system, avoiding the use of a large amount of hot water, and the present invention can be widely used in various medical units having different conditions; when
coupling between the liquid discharge joints and
coupling between the flushing joints are completed,
coupling between the steam female joint and the steam male joint is started, so that the liquid discharge joints and the flushing joints can achieve a positioning effect on coupling between the steam joints, avoiding the problem of low
fault tolerance when the three sets of joints are coupled at the same time, and also improving the coupling success rate.
